The dual-screen Nintendo DS portable became America's top-selling video game system of any type in June, according to independent sales tracker NPD Group. The introduction of the new DS Lite version boosted total sales to nearly 600,000 units, almost double that for any other game device.

According to Nintendo, DS popularity also is being propelled by a unique mix of software that appeals equally to mainstream players and those new to the category.

The company also reported that Nintendo Wi-Fi Connection, a wireless gaming network exclusive to Nintendo DS, has achieved 1.7 million users worldwide in eight months, an adoption rate far higher than any other game-play network to date.

"Nintendo DS is the only game system available a year ago that showed growth over the same period, and it did so in overwhelming fashion, with a leap of 426 percent," says George Harrison, Nintendo of America's senior vice president of marketing and corporate communications.
